I’m curious about the simulation of HEXA, and the simulator you provide looks very cool, but I think the simulator can do more than just design motions. For example, if we can get the data of the simulator, we can use machine leaning or reinforcement learning method to train it and transfer to the robot.So, could you tell me the tools you used to develop the simulator ?I think it is unity3d. I’m a newer to it and is there some useful advise to develop a similar simulator?Thank you very much.
